Abstract Purpose To study the macular features in Eales disease patients observed with fundus fluorescein angiography (FA), optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA). Methods A cross-sectional study was done on treatment naïve 31 eyes (23 patients) with Eales disease. Baseline parameters such as Best-corrected visual acuity (BCVA), slit-lamp bio microscopy (SLB), indirect ophthalmoscopy, FA, spectral-domain OCT {quantitative (central macular thickness [CMT]) and qualitative analysis on SD-OCT} and OCTA were performed. Any media opacity precluding the above investigations was excluded. Results Macular findings comprised of- epiretinal membrane, macular exudation, full thickness macular hole, sub internal limiting membrane bleed, cystoid macular oedema, neurosensory detachment and retinal thickening. Sixteen (51.6%) of our patients had macular changes as seen on all modalities together. SLB and indirect ophthalmoscopy missed macular findings in 50% patients and FA in 18.8% patients. OCT and OCTA diagnosed all macular findings. On comparison of mean BCVA in patients with macular involvement on FA, OCT and OCTA, compared to those without macular involvement, patients with macular involvement had lower BCVA (p 0.000, 0.01 and 0.001 respectively). Thus, FA missed many patients who had significant macular involvement and hence less vision. Conclusion Eales disease though described in literature as classically being peripheral retina disease process, also has macular involvement. OCT and OCTA are useful guides to evaluation of macular involvement in these patients. The latter seems to be superior to FA in detecting macular abnormalities in this ailment. OCTA is non-invasive and shows deep capillary plexus changes which are not shown by any other modality.


Even though the diagnosis depends on clinical examination, in cases with branch retinal vein occlusion (BRVO), fundus fluorescein angiography (FFA), optical coherence tomography (OCT), and optical coherence tomography angiography (OCTA) provide unique data for follow-up, management and prognosis. In FFA, delay of laminar flow phase in the involved branch, hyperfluorescence due to leakage from the vessel wall in the late phases, hypofluorescence due to the blockage by hemorrhage, and soft exudates, and hyperfluorescence due to macular edema can be detected. In OCT, macular thickening, cystic spaces, serous retinal detachment, hyperreflective dots, disorganization of the outer retinal layers – particularly the photoreceptor inner and outer segments line and the external limiting membrane – can be seen. OCTA reveals non-perfusion, particularly in the deep capillary plexus.

Purpose: To assess the current role of fluorescein angiography after the introduction of optical coherence tomography angiography in real-life clinical practice. Methods: This was a multicentric retrospective observational study to evaluate the number of fluorescein angiography and optical coherence tomography angiography procedures performed by different devices from January 2013 to December 2018. The centers involved were Centro Italiano Macula (Rome), and ophthalmology departments of University “G. D’Annunzio” Chieti–Pescara (Chieti) and “Azienda Ospedaliero Universitaria Careggi” (Florence). Results: Out of 19,898 total fluorescein angiography procedures performed in the observation period, 3444 (17.3%) were in 2013, 3972 (19.9%) were in 2014, 3601 (18.1%) were in 2015, 3407 (17.2%) were in 2016, 3285 (16.5%) were in 2017, and 2189 (11%) were in 2018. Out of 7949 optical coherence tomography angiography procedures performed in the observation period, none were performed in 2013, 550 (6.9%) were in 2014, 908 (11.5%) were in 2015, 2098 (26.4%) were in 2016, 2090 (26.3%) were in 2017, and 2303 (28.9%) were in 2018. Conclusion: Fluorescein angiography procedures were performed less often after the introduction of optical coherence tomography angiography technology. The ease, speed, and safety of the optical coherence tomography angiography procedure in everyday clinical practice have facilitated more optical coherence tomography angiography application compared to fluorescein angiography in recent years. In the future, we will probably evaluate the different pathologies that still need an evaluation by fluorescein angiography.

We describe a 7-year-old girl who developed exudation nasally to the right optic disc due to retinal arteriovenous malformation. Fluorescein angiography, spectral domain optical coherence tomography, and optical coherence tomography angiography were performed. We give an overview of the different imaging techniques and discuss the differential diagnosis. Since there was no visual impairment, no treatment was started. A spontaneous decrease in edema and exudation was noted after 6 months.
